  • Publication number: 20210373094
    Abstract: Exemplary embodiments are directed to magnetoresistive sensors and corresponding fabrication methods for magnetoresistive sensors. One example of a magnetoresistive sensor includes a layer stack, wherein the layer stack includes a reference layer having a fixed reference magnetization, wherein the fixed reference magnetization has a first magnetic orientation. The layer stack furthermore includes a magnetically free system of a plurality of layers, wherein the magnetically free system has a magnetically free magnetization, wherein the magnetically free magnetization is variable in the presence of an external magnetic field, and wherein the magnetically free magnetization has a second magnetic orientation in a ground state. The magnetically free system has two ferromagnetic layers and an interlayer, wherein the interlayer is arranged between the two ferromagnetic layers and includes magnesium oxide.

  • Patent number: 4380403
    Abstract: A closure cap for a writing instrument such as a ink pen and the like has an outer generally cylindrical cap housing within which is a sealing sleeve having a closed end to close one end of the cap housing. A slide sleeve of a hard rigid material is retained against axial movement within the sealing sleeve. A closure member of a soft resilient durable material is axially slideable within the slide sleeve and is acted upon by spring means which may include a helical spring or axially extending resilient strips.

  • Patent number: 4304330
    Abstract: A case for writing utensils and accessories consists of a base or receiving part into which the utensils and accessories fit, and a cover part which fits over the receiving part and projects upwardly from it. The upwardly projecting portion of the cover part forms an enclosed space into which the utensils and accessories can extend from the receiving part. The receiving part has protruberances extending outwardly from it which releasably interengage with openings in the cover part for locking the two parts together. A handle member is secured to the cover part so that the case can be easily carried.

  • Patent number: 4224000
    Abstract: A writing point assembly for a tubular drafting pen includes an elongated tubular shell from one end of which a tubular, capillary nib projects. A sliding weight guided in the shell axially bounds an ink storage space in the other end of the shell which is radially imperforate. Ink may flow from the storage space to the nib through an ink feeding channel between the weight and an inner shell wall. Threads on a first section of the outer, axial shell face permit the shell to be fastened in a tubular holder. A collar on the outer axial shell face is spaced intermediate the first face section and the nib center the shell in the holder. The collar defines a portion of an air channel axially by-passing the collar and communicating with the ambient atmosphere. A second axial portion of the outer face intermediate the threads and the other end of the shell defines a further portion of an air channel which communicates with the ink storage space.
